Overview of Cisco UCS-HD1T7K12G

The Cisco UCS-HD1T7K12G is a small-form-factor (2.5") enterprise hard disk drive engineered for UCS rack servers and other datacenter-class systems that accept hot-swap trays. It pairs a 1 TB capacity with a 7,200 RPM spindle and a 12 Gbit/s SAS interface to deliver a balanced mix of usable capacity, predictable rotational performance, and an interface designed for modern server backplanes and RAID controllers. This drive is commonly offered as a factory-new Cisco-branded part and appears in Cisco UCS C-Series and some UCS-integrated configurations. :contentReference[oaicite:0]{index=0}

Product features

Small Form Factor

The UCS-HD1T7K12G is designed for 2.5" bays and typically ships in Cisco-specific hot-swap trays so it installs directly into UCS C-series servers without adapters. The tray-centered design enables front-access serviceability — an essential requirement in high-density racks where minimizing downtime and drive handling is critical. Where vendors list the part, the product images and part number reference include the tray and latch assembly for rapid insertion and removal.

Enterprise mechanical build

Typical enterprise HDD construction applies: multi-plate media, vibration mitigation features compatible with multi-drive enclosures, and firmware tuned for RAID/dual-port environments. While rotational drives cannot match SSD I/O rates, their robust physical design, error recovery tuning, and lower cost per TB continue to make them valid choices for secondary storage tiers, archival volumes, and capacity-optimized nodes within UCS architectures.

Infrastructure

Throughput and latency

With a 7,200 RPM spindle and 12Gb/s SAS signaling, the drive offers predictable sequential throughput well-suited for large-block read/write tasks such as backups, media repositories, VM density hosts running low-IO VMs, and file servers that value capacity over IOPS. Random I/O performance will be lower than that of 10K/15K RPM SAS HDDs or enterprise SSDs; plan RAID and caching strategies accordingly to hide rotational latency for small-block, high-IOPS workloads.

Compatibility

Official server

Cisco’s C-Series UCS rack servers (including C220 and C240 variants) explicitly reference similar UCS-HD* drive part numbers in their configuration guides and spec sheets, and the UCS-HD1T7K12G is commonly listed in the SFF (2.5") HDD options for those servers. Always consult the target server’s hardware compatibility list (HCL) or spec sheet before purchase to confirm firmware revisions and backplane support.

Controller, backplane and RAID considerations

The 12Gb/s SAS interface is backward compatible with 6Gb/s SAS or SATA in many backplanes (though operation will be at the negotiated link rate). For optimal performance, pair these drives with controllers and backplanes that support 12Gb/s SAS and enterprise RAID features (up to RAID 6/60 for fault tolerance in capacity arrays). When designing arrays, factor in rebuild times for 1 TB rotational drives — rebuilds will be longer than with SSDs and should influence RAID level choice and spare count.

Comparison

UCS-HD1T7K12G compares to other media

Compared to enterprise SSDs, this 1 TB 7.2K SAS HDD offers lower cost per GB but higher latency and lower IOPS. Compared to 10K/15K SAS HDDs, it provides higher capacity per spindle with slightly reduced rotational speed — a tradeoff that benefits capacity-optimized tiers. When comparing to SATA alternatives, the 12Gb/s SAS interface and enterprise firmware of the Cisco part typically make it more suitable for RAID arrays and datacenter backplanes where SAS is preferred for its enterprise feature set (dual-port/expander support on SAS in certain models).

Essential product content

On any category or product page for this drive, include: full specs table (capacity, RPM, interface, form factor, device type), compatibility list (supported UCS server models), part number (UCS-HD1T7K12G or UCS-HD1T7K12G= where applicable), images showing the drive with tray, links to spec sheets or server compatibility PDFs, and a short usage guide (recommended RAID configurations and monitoring best practices). These elements help both buyers and search engines understand utility, compatibility and purchase readiness.
